Decision Making in the Tea Leaves Diseases Detection Using Mamdani Fuzzy Inference Method

Abstract

The tea plants (Camellia Sinensis) are small tree species that use leaves and leaf buds to produce tea harvested through a monoculture system. It is an agriculture practice to cultivate one types of crop or livestock, variety or breed on a farm annually. Moreover, the emergence of pests, pathogens and diseases cause serious damages to tea plants significantly to its productivity and quality to optimum worst. All parts of the tea plant such as leaves, stems, roots, flowers and fruits are exposed to these harm lead to loss of yield 7 until 10% per year. The intensity of these attacks vary greatly on particular climate, the degree slope and the plant material used. Therefore, this study analyzes tea leaves as a common part used in recipes to create unique taste and flavor in tea production, especially in agro-industry. The decision making method used is Fuzzy Mamdani Inference as one of model with functional hierarchy with initial input based on established criteria. Fuzzy logic will provide tolerance to the set of value, so that small changes will not result in significant category differences, only affect the membership level on the variable value. Previous method using probabilities have shown 78% tea leaves have been attacked by category C (Gray Blight) while using Mamdani indicated 86% of tea leaves have been infected. In this case, this result pointed out that Fuzzy Mamdani Inferences have more optimal result compare to the previous method.

Utilization of Color Space Value Filter for Laser Pointer Spot Detection with a Single Board Computer

“…Selain itu, dapat dikembangkan seperti pemanfaatan laser pointer untuk mesin interaktif (Londhe, 2014) (Aizeboje, 2015) (Konig, 2019), deteksi objek spot laser pointer dengan bantuan pustaka OpenCV pada bahasa pemrograman (Nakhoda, 2014). Selain itu, tulisan tentang penggunaan ruang warna seperti deteksi buah dengan metode Hue filter (Rahmadewi, 2019), citra parasit malaria dengan HSV filter (Sulistyawati, 2018), citra kue tradisional (Enggarwati, 2019), temu kembali citra batik (A. Y. Wicaksono, 2013), kecerahan citra digital (David, 2019), penyakit daun teh (Lubis, 2018). Sumber berkas cahaya fokus yang dihasilkan oleh laser pointer dapat membentuk spot cahaya terang jika diarahkan ke bidang yang tidak menyerap cahaya.…”

Sensitivity of shortest distance search in the ant colony algorithm with varying normalized distance formulas

“…So, it is necessary to review the ant colony algorithm by measuring distance and finding the shortest distance with some normalized distance formula to find the optimal value. And in the future this paper can become the foundation of the process of big data and forecasting techniques in order to improve the process of intelligence and data science [25]- [27].…”

Optimization of Applied Detection Rate in the Simple Evolving Connectionist System Method for Classification of Images Containing Protein

“…Meanwhile, many methods in digital image processing to explain data from an image by applying computer vision to explain data both manufacturing, medical, agriculture, and others that will be studied by the computer as computer knowledge [6]. One example carried out by reference [7] is to detect pests from tea leaves which are a good requirement of everyday human protein.…”
